Routers without firmware updates remain functional but face growing security risks
Security experts warn that routers continuing to operate after manufacturers stop releasing firmware updates are vulnerable to unfixed flaws and potential attacks.
Hardware continues to function normally
A router will keep connecting devices to the internet even if the manufacturer stops providing new software. The hardware itself does not fail simply because update support has ended. There is no automatic mechanism that turns the device off once updates cease.
Unfixed security flaws create exposure
Once regular firmware releases stop, the router loses its primary method for fixing newly discovered security issues. Attackers often target these vulnerable devices in bulk to relay malicious traffic or join larger compromised groups. Owners should disable remote administration features to reduce the risk of external access.
Replacement becomes a priority over time
A device without updates is not automatically compromised, but it remains vulnerable with every passing day. Experts suggest replacing the router sooner rather than later as potential exposure risks continue to grow. Five years serves as a checkpoint for considering whether a router is still appropriate for use.
